STORAGE-BUILDING.

Application filed May 22, 1919.

To all whom. it may concern:

Be it known that I, (lnonoi: I. Hum, 21 citizenof the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Storage-lluildings, ofwhich the following is a specification, referones being had therein tothe accompanyin drawing.

10 his invention is a novel storage building, and refers more especiallyto the structure and .form of a building for storing and handling bymeans of cranes materials in bulk, of which fertilizers may be taken as16 example. The main objects of the inve'ntion are to afford a storagebuilding which; is economical of structure, ample iniivailuble storagespace, well adapted for the operations of the crane and safe from 20liability tosu'chinjury as'frequently occurs tostorage buildings fromthepressui'c of the stored materials. Other and further objects andu'dv'antagejs of the" resent invention will be 'made'clear in the.ereinaftor following 23 description of ubuildingi; in which thepres entinvention is embodied, or will be apparent-to those skilled in the art.

To the'attainment of such objects and advantagesthe present inventionconsists in 80 the novel storage building and the novel features ofstructure, arrangement, and combination herein deswribcd or illustrated;In't'he accompanying, drawings forming a part hereof, the gii'iglefigure is a more or less 85 diagrammatic transverse section andclovetion of a storage building, embodying the principles of the presentinvention.

It will be understood that the buildin may be of any desired-length, thelen 40 being increased at will by" the addingof units or sections, toeach of which the present. invention is applicable.

Referring to the drawings, the main columns 10 at the opposite sides ofthe build ing 'xnaybe multiplied longitudinally as far asdesircdyaccordingto the length o'f the building. These columns are shownas supporting outer side walls 11. As will be explaincd, however. thes'eside walls donot ex-' to tend entirely to the base, so that the spacebetween the lower ends of the columns is open. Extending across fromside to side are the roof'trusses 1-2,.with any suitable roofing andconcomitnnts,as may be desired.

At the opposite interior sides of the building are the loo itudinalbeams or tracks 13, on which i-untie \vheelsat the ends of the cranegirder or bridge 14. As u f). the crane is indicated a carriage 15,whiclrmay slide or roll transversely along the length of the girder 14,and from the carriage hangs the bucket 16, which may be lowered andelevated, and pnened and closed in the usual manner. By e u anddoivn,the transverse, and the longitudinal movements described, thebucket is capable of reaching, every portion of the building with thetrifling exception hereafter noted. It reaches every ioint between theopposite upright side we ls, 11, and it will be observed that below theoverhead crime the space between the side walls is free and unobstructedfor the operations of the crane. The purpose of the crane 'is to serveas an overheadv conveyor, either for'int'roducing the fertilizer orother material inthe'form of a. pile or for rem'oving it, and theparticular form and operation of the illustrated conveyor are not hereinclaimed. r

' The side walls 11 may be of very cheap construction, as they aremerely protective and receive no strain. These are shown as terminatingat a. point above the flooring, which is approximately half the/heightof the desired pile of stored materiel. From this point extendingoutwardly and down- Iwardly, preferably at a slant, are the shedextensions 17 at each side, these also being merely protectivein nature,and cheap and light of construction. These, as will be seen, receive ateachside. the toe of the piled material. It is herein assumed that thepiled-up material will have at its sides a slope of a. proximately 45.For a substantially ifi'erent slope or' angle of repose. of the materialbeing stored, the ex tent of the side walls 11 and the shape of thesheds 17 might be correspondingly alrerec.

" By a'iough line 18, I have indicated the approximate form ofthe sidesofthe pile of stored'meterial which can be accommodated in the describedstorage building, and by 19 the'preferred form of the top of such pile,it being shown truncated. In some cases the pile might 'be continued toa central apex,-es indicated by the dotted lines 20, but this wouldrequire the roof, the

rial could not be crane, aml therefore the buildin as a whole to be thatextent higher, with relatively small gain of storage volume,disproportionate to the added cost o't' the structure. I prefer thebuilding and the stored pile to b substantially as shown in full lines,this giving a substantially greater \olumc of storage. for the cost ofthestrurturc than any building heretofore known with which preferablyapproximately twice the height material, that is, b:

of the pile of stored 2a. At least the width is materiallyreater thanthe height of the pile, so that y the use of the extension sheds thepile will have a truncated form. I

The im ortance of the shed extensions 17 will now assuming the sidewalls 11 to extend straight to the ground, these being of light andcheap construction would not s cc to serve as a retaining wall. In otherwords, the matepiled up to the hei ht in- The dotte lines dicated by thelines 18.

- 21 indicate a triangle which is approxi cause walls to diverge, to thmately the maximum stora space that would be available. Under t eassumed dimensions this would be {,aXb cubic feet per foot of length ofthe' building. With such a building the only agevolume' could beincreased would be to replace the side walls .11 by solid andexpcnsively constructed retaining Walls. Many stored materials tend toexpand laterally, not merely from mechanical pressure, but fromexpansion within the mass, or equivalent known to expand to such anextent as to' e permanent injury of the building. It is one of theadvantages of the present invention that the necessarily heavy retainingwalls, to avoid this, are wholly dispensed with, and a structure whichis light,

temporary will adequately serve.

the employment of the shed extension B 17 this result is attained,because the material may now be piled up to the point indicated by thelines 18, .19 the natural form that the piled material will take. Thematerial extends outwardly be yond the columns 10, and into the sheds1'2, as indicated. The pile being of natural e explained. Without these,and

, ical handling mode in which the storaction.- Fertilizer has been'inexpensive, or even and 18. This is and in fact the side walls, take nopressure whatsoform, the sheds, are required to ever.

It will readily be seen that the stora e volume by the present inventionwill Es approximately 11X?) cubic feet per foot of building length, thatis, twice the volume available with an ordinary building in which thematerial is piled, as indicated by the dotted lines 21. Moreover, thispractically double storage capacity is at relatively no additionalexpense, as the shed walls 17 are cheap and easily constructed, and theysubstantially merely replace the omitted lower portions of the sidewalls 11. Moreover, every part of the stored material will be readilyaccessible to the crane buckets, with the exception of a portion of thematerial beneath the shed walls 17, and this is of very smallproportionate amount and easily made accessible by other means. Theincreased volume accessible to the crane, it will be noted, is affordedwithout any increase whatsoever in the travel of the crane itself.

It will, thus be seen that I have described a storage building embodyingthe rinciples and attainin disadvantages of t 0 present invention. incemany matters of design, arrangement, structure and combination may bevariously altered without do arting from the principles, it is notintend invention tosuch features exce as set forth in the appendedclaims.

What is. claimed is: t}

1. A building for the storage and mechanof bulk material, consisting ofthe body of the buiidin -supported by upright columns, opposite uprightside walls extending from the roof 'down to a point substantially abovethe floor, free unobstructed space between the opposite side walls formovements of a handhn apparatus above the piled material, a mec anicalhandling apparatus operating between such side walls, and an exteriorlean-t0 shed, the walls of which are continuations of said side walls,and into which the toe of th piled material zna extend.

2. A storage bui ding for storing bulk ma; terial in pile form, the samehav ng an in,- terior overhead conveyor arranged to 0 erate between theopposite walls to intro uce material in the form of a pile or to removesuch material, main side walls giving free s ace for the conveyormovements between in em and above the pile, and outward wall and he. a.

to limit the a t in so far extensions at the lower opposite sides ofthe' pile of 8 even building adapted for sj jring depth,

for the operations of a crane. an interior overhead bucket crane locatedabove the pile and arranged to travel longitudinally and laterally togive access to all points between the opposite side walls forintroducing or removing material. and external shed extensions at thefoot of the opposite side walls to receive the toe of the pile atQ'Rt'll side.

4. A storage building for storing bulk material in the form of atruncated pile of given depth. the same having opposite side wallsspaced farther apart than the pile and an interior overhead conveyorarranged to operate between the opposite walls; said side walls havingtheir lowen portions provided or formed with outward wall extensions atthe lower opposite sidesof the building adapted to receive the toe ofthe pile ateach side, and thereby permit the material to be piledsubstantially as shown, without injurious side pressure against thewalls.

tweenlhe column lines A storage building having overhead handling meansoperatin longitudinally and laterally within the building walls tointroduce in the form of a pile and remove bulk material, and comprisingthe upright columns, roof and generally u )right inclosing walls,constructed to give ree space bet'or the operation of thematerialhandling means, at least. one of the longitudinal inclosing wallsextending do'wmvardly below the roof and being at its lower portiondisposed beyond the column line, to form a longitudinal shed to receivethe toe of the piled material, whereby the stored material may be piledso high within the building as to extend substantially beyond the columnline without injurious pressure against the wall.

In testimony whereof, I have affixed my signature hereto.
